This document summarizes a study on developing a biodegradable low-density polyethylene (LDPE) using potato starch. Key findings include:
- Potato starch was blended with LDPE to produce a composite material that showed increased biodegradability compared to pure LDPE.
- Samples of the potato starch-LDPE blend buried in soil for 8 months showed weight loss, indicating biodegradation from soil microorganisms.
- Fourier transform infrared spectroscopy analysis confirmed biodegradation had occurred, with a reduction in carbonyl group peaks from the potato starch.
- Exposure to the bacteria Pseudomonas aeruginosa also resulted in weight changes providing further evidence of microbial degradation of the composite material.

The document also outlines the physical and chemical properties of PHB, compares it to other bioplastics and conventional plastics, and discusses current and potential applications. In conclusion, it addresses that while bioplastics are generally more expensive than regular plastics, the environmental benefits and developing technologies could make their costs more competitive over time.
Ppt of biodegradable packaging
Biopolymers can be divided into three categories based on their origin and production:
1) Polymers directly extracted from biomass like starch and cellulose
2) Polymers produced from biobased monomers through chemical synthesis like polylactic acid
3) Polymers produced by microorganisms or genetically modified bacteria like polyhydroxyalkanoates
Common biopolymers include starch, polylactic acid, polyhydroxyalkanoates, and polycaprolactone. These materials have properties similar to conventional plastics but are biodegradable. Their gas barrier and thermal properties depend on material and humidity conditions. Biopolymers can be composted within weeks to months depending on
Biopolymer
The document discusses biopolymers, which are polymers produced by living organisms. It covers various types of biodegradable polymers including synthetic polymers like polylactic acid (PLA) and natural polymers like starch. The mechanisms of polymer biodegradation are described. Applications of biodegradable polymers in areas like biomedical, packaging and agriculture are also mentioned. Factors affecting the biodegradation of polymers are discussed. Current trends in biopolymers including their use as alternatives to petroleum-based plastics are summarized.
Sustainability of the chosen product
Mango Materials produces biodegradable plastics from waste methane that are competitive with oil-based plastics. Their plastics can be recycled by degrading back into methane in wastewater treatment or landfills, closing the loop. Mango Materials makes poly-hydroxybutryate (PHB) plastic into products like toys and packaging. They utilize methane from anaerobic digestion of waste at treatment plants or landfills rather than genetically modified feedstocks. Their plastic biodegrades depending on environment and thickness.
Biopolymers
Biopolymers are polymers produced from natural sources and include polysaccharides like cellulose, starch, and carbohydrate polymers produced by bacteria and fungi, as well as animal protein polymers like wool, silk, gelatin and collagen. There are four main types of biopolymers based on starch, sugar, cellulose, and synthetic materials. Commercially available biopolymers include polylactic acid, which is an aliphatic polyester made from lactic acid obtained via bacterial fermentation of corn or sugars. While polylactic acid has mechanical properties similar to traditional polymers, its thermal properties are less attractive.
